Why Would My Motorcycle Exhaust Have Grey Smoke

Why Would My Motorcycle Exhaust Have Grey Smoke?

Certain motorcycles always emit some type of fumes upon starting the engine. However, grey smoke signals a problem with the engine and necessitates prompt investigation to avoid serious engine damage.

Clogged Air Filter

    A clogged air filter causes dark smoke to come out of the exhaust pipes. If this is the cause of the smoke, then the bikes spark plugs will also not work. Change the motorcycles filter to remedy the situation.

Open Starter Plunger

    An open starter plunger can also result in grey smoke from motorcycle exhaust pipes. The starter plunger is a small component of the starter. Repair this problem by removing the bolts from the starters cover to reveal the component. Push the plunger closed and replace the starter cover.

Float Bowl Fuel Levels

    Grey smoke can result from improper fuel levels in the float bowl of the carburetor. Remove the float bowl from the carburetor by taking out the screws. Check the markings on the float bowl to ensure the fuel levels are correct.
